CVE-2025-11002
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · unedited7-Zip ZIP File Parsing Directory Traversal Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of 7-Zip. Interaction with this product is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists within the handling of symbolic links in ZIP files. Crafted data in a ZIP file can cause the process to traverse to unintended directories. An attacker can leverage this vulnerability to execute code in the context of a service account. Was ZDI-CAN-26743.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThis is a directory traversal vulnerability in 7-Zip's ZIP file parser where symbolic links within crafted ZIP archives can cause the extraction process to traverse beyond the intended target directory. By embedding malicious symbolic link entries in a ZIP file, an attacker can cause 7-Zip to write files to arbitrary locations on the system, achieving code execution in the context of the user running 7-Zip (often a privileged service account).

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate 7-Zip installationSearch for 7z.exe in common installation directories (C:\Program Files\7-Zip, C:\Program Files (x86)\7-Zip) or check Start Menu shortcuts; use 'where 7z' command on Windows or 'which 7z' on LinuxAffected if 7-Zip is found on the system
-
Determine installed 7-Zip versionRun '7z' or '7z.exe' with the version flag: '7z -version' or right-click 7z.exe, select Properties, and view the Details tab for Product VersionAffected if Unable to retrieve version information
-
Compare version against CVE entryCheck if the installed version is exactly 24.09; note that this CVE affects only version 24.09Affected if Installed version is 24.09
You are affected if 7-Zip version 24.09 is installed on your system and you extract ZIP files from untrusted sources.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataDo not extract untrusted ZIP files with 7-Zip until a vendor patch is available; run 7-Zip with least-privilege user context and monitor extraction operations.
